An object moves 15.0 m north and then 11.0 m south. Find both the distance traveled and the magnitude of the displacement vector.

How much work does the force of gravity do in pulling a 10 kg box down a 30º inclined plane of length 8.0 m? Note that sin 30 = cos 60 = 0.500 and cos 30 = sin 60 = 0.866. Can someone explain this one?

How does the force due to gravity on Mars compare to the force due to gravity on Earth?, and Using Newton's Second Law, explain how a rocket can have an increase in acceleration over time.

Two long, straight wires are parallel and 26 cm apart. If each wire carries a current of 57 A in the same direction, what is the magnitude of the magnetic force per meter (in N/m) exerted on each wire?

To investigate seed growth in different levels of light, Jarrod covers seeds with soil in three different containers.

The Huka Falls on the Waikato River is one of New Zealand's most visited natural tourist attractions. On average, the river has a flow rate of about 300,000 L/s. At the gorge, the river narrows to 20-m wide and averages 20-m deep.

Name six processes that are often involved in scientific inquiry.

What happens to the ball's velocity while the ball is traveling upwards?

What will happen to this current if a magnet is brought near the cord?

A 2.0 kilogram rifle initially at rest fires a 0.002 kilogram bullet. As the bullet leaves the rifle with a velocity of 500 meters per second, what is the momentum of the rifle - bullet system?
